Google Launches Interactive Map of Mars
By ALICIA CHANG AP Science Writer

LOS ANGELES (AP) -- First there was Google Earth, then Google Moon. On Monday, Google Inc. expanded its galactic reach by launching Google Mars, a Web browser-based mapping tool that gives users an up-close, interactive view of the Red Planet with the click of a mouse.

The Martian maps were made from images taken by NASA's orbiting Mars Odyssey and Mars Global Surveyor.

Google Mars doesn't provide driving directions, but users can see the planet in three different formats: The Martian elevation map is color-coded by altitude; the visible-imagery map shows the surface in black-and-white pictures; the infrared map indicates temperature, with cooler areas dark and warmer areas bright.

Users can also zoom in on any of the three maps to view geographical features such as mountains, canyons, dunes and craters. The maps also pinpoint the locations of unmanned space probes that have landed on Mars. Story
